ESP8266 Project Powered Up

As I said in the previous post, I wanted to get a power supply for the ESP8266 project instead of using batteries. I decided to go to the nearby electronics store today to get one.This power supply is 9VDC 1A and actually comes in a branded box for the Atari “Lynx”, an old portable gaming system from the 80’s. I’m curious to know if the newer (I’m assuming) and smaller power supplies that were also in the store are any better than this one in terms of efficiency. I bought this one because of the cheaper price and it has the CSA and UL listings which is nice to have.

I also picked up a new soldering iron tip, and the 9V battery clips came in the mail today. I used all of these things to get the power supply into the project.I soldered the power supply wires to one of the 9v battery clips backwards so it would clip into another battery holder that would be the power input to a project. This way, the project can still go battery powered if I wanted to move it somewhere away from any power outlets temporarily. The power supply can also be shared around to other projects if it even needs to be.

With the project powered up from the wall, I have it uploading information again. You can view my Thing Speak channel here. The code is available on GitHub if you’d like to try a similar project.

I am waiting for some switches in the mail, along with other things I don’t really need anymore (parts for the temperature sensor that was supposed to be for this project). Anyways, I want to add a switch to the LCD backlight so I can essentially turn off the LCD when I don’t want it on. That would be the last connection in the prototype. From there, I’ll need to decide what will be soldered where and try to get it into an enclosure.
